The application of low pressure boiling technique could increase wort boiling temperature to 100.5 ℃ and advance protein agglomeration and reduce solidifiable nitrogen content to 0.5 mg/100 mL. Maillard reaction and Brown reaction were strengthened in the boiling, melanoidin and melanoid compound contents increased, wort chromaticity improved, and the oxidation resistance of wort strengthened. Besides, the boiling intensity dropped from 9 %～12 % to 7 %～8 % and boiling time shortened to 10～20 min, which improved production efficiency and saved 20 % energy and improved beer non-biological stability.
